My MacBook will not turn on and when I connect the charger it has a very dim light

Question

I have just come back from holiday and went to turn on my MacBook, but it will not turn on
I connected my charger and the light is very very dim.
How do I resolve this? Will I end up losing all I have saved on it? Please help!!!

There may be something corrupted in the system, and a certain kind of reset may be able to help...
•Intel-based Mac: Resetting the System Mangement Controller (SMC)

If that doesn't work, check instructions carefully and repeat if necessary, see about taking the computer to an Apple Store and try to call ahead for Genius appointment; or contact an authorized reseller with product specialists and service.
Some users ventured into their out-of-warranty macbooks to check the actual cables going from the battery compartment to the logic board, apparently some batteries unplug. Others you can't get into.
I see following post/link says several things, can't vouch for any except ^ the SMC reset support page above: https://discussions.apple.com/message/23996241#23996241 - Also, check the right side in this recent thread for links to similar topics.
{In order to make a backup at this late a date, you'd need power to the computer; enough to try & see if something as quaint as 'Target Disk mode' would work... If your Macbook is one with Firewire ports.}
•How to use and troubleshoot FireWire target disk mode:

With FW TDM, the failed computer can sometimes be powered up holding the T-key down, and a firewire icon would appear on the screen; then one could go about attaching or using a FW cable of correct type and connect it to another capable computer, then the failed computer's HDD would appear as an external drive. In the past, it was possible to clone or copy a drive from a computer that won't boot to another hard disk drive. Or at least copy stuff of that does not require the system to function along with the saved files.
Good luck & happy computing!
